Caching Query Strings
WP Rocket does not cache pages with query strings by default, although there are some very specific exceptions (see below).
A query string is where you have a URL that contains a question mark followed by a parameter and a value, like this:
In this case,
country is the parameter and
italy is the value.
If you want these types of pages to be cached, go to the Advanced Rules settings tab, and add each parameter in the Cache Query String(s) text field (one per line):
When you do this, a dedicated cache file will be generated for each value the parameter
country receives in a URL.
A query string can also contain multiple parameter/value pairs, chained by
& characters. Example:
Ignored query string parameters with standard caching
For all of the parameters listed above, WP Rocket will ignore the query string and serve the standard cache file, regardless of any parameter values in the URL. Here’s what that means:
example.com/about-us/?gclid=something example.com/about-us/?gclid=somethingelse // will BOTH receive the cache file from: example.com/about-us/
Please note: A dedicated cache file will be created when the parameters found in the dedicated caching section below or those placed on the Advanced Rules tab referenced above are included in the URL.
Parameters with dedicated caching
For all of the parameters listed above, WP Rocket will serve the dedicated cache file, depending on the parameter values in the URL. Here’s what that means:
example.com/about-us/?lang=english example.com/about-us/?lang=french // will create a dedicated cache file for their parameter/value pairs: ?lang=english ?lang=french
Search Results (dedicated caching)
The standard parameter for WordPress search results is:
However, the Cache query strings option will not enable caching for this parameter. To cache search results, please install the helper plugin found here.
